Abstract

Provided are a method and device that identify characteristics of data to be sent by a user equipment and send small-sized data via a control message. The data transmission method for the user equipment may include: generating IP data; determining whether the IP data corresponds to small data that has a size less than or equal to a preset reference size or matches identification information of a preset service; and transmitting the IP data through a connection management (CM) layer to the network by use of a control message.

Claims

1. A method of data transmission for a user equipment, the method comprising:

generating IP data;

determining whether the IP data satisfies a preset criterion; and

sending, when the IP data satisfies the preset criterion, the IP data through a connection management layer to a base station by use of a control message.

2. The method of claim 1, wherein determining whether the IP data satisfies a preset criterion comprises checking whether the IP data satisfies the preset criterion by use of a small data packet filter, and wherein the small data packet filter checks whether the IP data satisfies the preset criterion on the basis of at least one of an indication to whether the IP data is UDP data or TCP data, the size of the IP data, the address of a server configured to receive the IP data, the port number of the server, the type of the service provided by the server, and the identifier of the service.

3. The method of claim 1, wherein sending the IP data comprises transmitting the IP data through the connection management layer to the base station by use of a NAS control message.

4. The method of claim 1, further comprising checking, when the IP data does not satisfy the preset criterion, whether the IP data matches one of one or more packet filters whose filtering criteria are different from the preset criterion.

5. The method of claim 1, wherein determining whether the IP data satisfies a preset criterion comprises:

checking whether user interaction is present in relation to the IP data; and

determining that the IP data is small data when user interaction is not present in relation to the IP data.

6. The method of claim 5, wherein checking whether user interaction is present comprises determining that user interaction is not present in relation to the IP data when the difference between the occurrence time of user input or output and the generation time of the IP data is greater than or equal to a preset time value.

7. The method of claim 5, further comprising transmitting, when the IP data matches one of the packet filters whose filtering criteria are different from the preset criterion, the IP data by use of a bearer mapped with the matching packet filter.

8. The method of claim 5, further comprising dropping the IP data when the IP data does not match any one of the packet filters whose filtering criteria are different from the preset criterion.

9. A user equipment supporting data transmission, comprising:

a transceiver unit to send and receive signals to and from a base station; and

a control unit to control a process of generating IP data, determining whether the IP data satisfies a preset criterion, and sending, when the IP data satisfies the preset criterion, the IP data through a connection management layer to the base station by use of a control message.

10. The user equipment of claim 9, wherein the control unit comprises a small data packet filter, and wherein the small data packet filter checks whether the IP data satisfies the preset criterion on the basis of at least one of an indication to whether the IP data is UDP data or TCP data, the size of the IP data, the address of a server configured to receive the IP data, the type of the service requiring IP data, and the identifier of the service.

11. The user equipment of claim 9, wherein the control unit controls the transceiver unit to transmit the IP data through the connection management layer to the base station by use of a NAS control message.

12. The user equipment of claim 9, wherein, when the IP data does not satisfy the preset criterion, the control unit checks whether the IP data matches one of one or more packet filters whose filtering criteria are different from the preset criterion.

13. The user equipment of claim 9, wherein the control unit checks whether user interaction is present in relation to the IP data, and determines that the IP data is small data when user interaction is not present in relation to the IP data.

14. The user equipment of claim 13, wherein the control unit determines that user interaction is not present in relation to the IP data when the difference between the occurrence time of user input or output and the generation time of the IP data is greater than or equal to a preset time value.

15. The user equipment of claim 13, wherein, when the IP data matches one of the packet filters whose filtering criteria are different from the preset criterion, the control unit transmits the IP data by use of a bearer mapped with the matching packet filter.

16. The user equipment of claim 13, wherein the control unit drops the IP data when the IP data does not match any one of the packet filters whose filtering criteria are different from the preset criterion.
